I am trying to optimise the parameters. The Quality Measure and the Pruning from the Decision Tree Learner Node.
Example for the Quality Measure to test whether the Gini Index or Gain ratio leads to a higher accuracy.
To do this, I have the parameter in the optimisation loop, then I try to define the whole thing in the rule engine, but unfortunately this doesn’t work, do you know why this could be?
I cant select Replace Column and get an error all the time.
Hi
If you export your data in resetted state no one can see have a look at your issue because the data is missing.
Quality Measure does neither appear in your column list nor in your flow variable list so you can’t reference that in your filter rules

You need to add the table row to variable after number to string and feed that into the learner node.
Also split criteria requires a string like “Gini” and not a number. Replace the name Quality_Measure in your rule engine with something else e.g. abc and use this column in the variable (split criterion) configuration in the learner.
